Nested tags with a List of Objects

Question

I'm having trouble getting nested tags to work. Here's an example:
My form has a List that contains a Bean called Car as well as a getter and a setter. The Car Bean has three String attributes: color, model and manufacturer. Getters and setters are present.
When I navigate to the form, my Action class creates a single Car and adds it to the list: when the page loads I am presented with three text fields representing my Car bean. Good.
However when I enter some text into the fields and hit the save button I get the following error:
Error 500: BeanUtils.populateI've read a bit about nested tags but still I can't figure out what exactly I'm doing wrong.
Here is a small sample of the JSP code;
<html:form action="/addCar.do">
<nested:iterate name="carForm" property="carList" type="com.foo.bean.CarBean">
  <nested:text property="color"></nested:text>
  <nested:text property="model"></nested:text>
  <nested:text property="manufacturer"></nested:text>
</nested:iterate>
</html:form>Should I be doing something else to properly use a nested tag? Please let me know if more details are required.
Thank you,
David

I am using crystal reports to show names of a bunch of people. insted of each name comes form different function inside the oracle package, I would like to have a single function with an array of names so that I can return it easily
eg; board member 1 (from function 1)
board member 2 (from function 2)
board member 3 (from function 3)
I should get something like board member n(from a single function that has n number of members) , so that its easy for managing the list later and reduce the code
This sounds so silly, but i am new to both crystal and pl/sql....
please help
